    External temperature sensor question.

    Hey all quick question, does anyone know if the external temp sensor in the front bumper on the mk4 does anything other than supply the readout for the dash display? Im wondering as since i replaced mine which was showing 30 or so decrees over the recent cold spell my engine seems to be running much smoother...

    I know the ecu reads the air temp for fuelling but i thought this was from a sensor on the air intake...

    Any thoughts?

    this sensor is purely for the MFD readout, coolant and air temp sensors control the engine via the ECU

    Thought as much, must be the placebo effect like how im sure the motor got faster when I put my new leather gear gaiter in! Lol...
